Myths about pregnancy are as common as cravings and nausea: someone always has a remedy or a recommendation to give you. And what to say if you are a first-time mother!
That if you do a lot of exercise you can advance the delivery, that the shape of the belly reveals the sex of the baby, that eating spicy helps to give birth, that it is easier to get pregnant at full moon... the list is long.
Over time, skepticism began to beat the pulse of what is often considered popular wisdom and shifting credibility to science. And while most superstitions of pregnancy are false, your aunts and grandmothers were right in these three myths, which were compiled by the journal Science of Us. Yes, they are "scientifically proven"!
Difficult labor? It's a boy!
Honestly, the researchers are not very sure of the reason for this finding. However, as reported by Science of Us, after analyzing more than 8,000 births in a hospital in Ireland between 1997 and 2000, a group of doctors observed that the labor lasted for less than six hours, The children exceeded that period. The study did not include mothers who gave birth prematurely or those who were given birth.
In addition, women delivering children were more likely to have complications: 29% of childbirths required some extra intervention, while for girls the percentage was 24%. And one possible reason for this is that children on average weigh 85 grams more than girls. Now, another study also revealed in 2003 that male mothers consume more calories during pregnancy, a fact that suggests that children are more demanding even during gestation.
Do you want a girl? Goodbye bananas!
Eating a lot of food in the pre-gestation period means that the odds of a child are increasing. Research published in the journal Proceedings of the Royal Society in 2008 evaluated 740 women with first-time pregnancies, based on the diet they had a year before conception. Evaluating the number of calories ingested, they divided them into three groups: those in the upper group gave birth to children in 56% of the time, while those in the lower set had girls 55% of the time.
Researchers also noted that, in addition to calories, other specific nutrients could also determine the sex of the baby: such as potassium, that's why bananas. Ingesting this element, as well as calcium and sodium, increased the possibility of giving birth to a child.
Acidity in the stomach? Yes, it's a sign of a furry baby
A team of researchers from Johns Hopkins University followed 64 pregnant women during 2006. The study for Birth magazine reported that 28 of them reported moderate or severe heartburn and when babies (surprise!) Gave birth Of 23 of those mothers had hair similar to the average or even more abundant. In addition, 10 of the 12 who did not feel heartburn had babies with less hair than the average.
However, Science of Us explains that this is a perfect example that the relationship between two factors does not necessarily mean that one is the cause of the other. The acidity and amount of hair were actually due to the hormones of pregnancy: the same are the ones that regulate the growth of hair in the uterus and those that relax the muscles that hold the acid inside the stomach.
